Alarm – general information
The alarm system provides a warning if an attempt is made to break into the vehicle. The alarm is automatically armed (p. 165) whenever the vehicle is locked with theremote key. When armed, the alarm continuously monitors a number of points on the vehicle. The follow-ing conditions will trigger the alarm:
• The hood is forced open.
• The tailgate is forced open.
• A door is forced open.
• The ignition slot is tampered with.
• An attempt is made to start the vehicle with a non-approved key (a key notcoded to the car's ignition).
• The battery is disconnected (while thealarm is armed).
• The siren is disconnected when the alarmis disarmed.
A message will appear in the information dis- play if a fault should occur in the alarm sys-tem. Contact a trained and qualified Volvoservice technician.
NOTE
Do not attempt to repair any of the compo- nents in the alarm system yourself. Thiscould affect the insurance policy on thevehicle.

Radar sensor
The radar sensor is designed to help detect cars or larger vehicles driving in the samedirection as your vehicle, in the same lane.
The radar sensor and its limitationsIn addition to being used by the AdaptiveCruise Control (ACC), the radar sensor is alsoused by Distance Alert (see Distance Alert –introduction (p. 193)) and Collision Warningwith Full Auto-brake and Pedestrian Detec-tion (see Collision warning – introduction(p. 204)).
WARNING
•If there is visible damage to the front grille or you suspect that the radarsensor may be damaged in any way,contact a trained and qualified Volvoservice technician as soon as possible.The radar sensor may only functionpartially (or not at all) if it is damagedor is not securely fastened in place.
• Accessories or other objects, such asextra headlights, must not be installedin front of the grille.
• Modification of the radar sensor couldmake its use illegal.
The radar sensor's capacity to detect vehi- cles ahead is impeded:
• if the radar sensor is obstructed and can- not detect other vehicles, for example in heavy rain, or if snow or other objects areobscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor clean.
•
if the speed of vehicles ahead is signifi- cantly different from your own speed.

Adaptive Cruise Control – limitations
The ACC cannot cover all driving situations and traffic, weather and road conditions.
Situations where ACC may not function optimally
WARNING
• The radar sensor has a limited field of vision. In some situations it may detecta vehicle later than expected or notdetect other vehicles at all.
• If ACC is not functioning properly,cruise control will also be disabled.

an audible signalThe vehicle is at a standstill and ACC will release the brakes before the parking brake engages to keep the vehicle stopped but a problem with the parking brake means that the vehicle may begin to roll. The driver will have to apply the brakes. The message will remain in the display and the audible signal will continue until the driver applies the brakes or presses the accelerator pedal.
-Below 30 km/h Only followingThis is displayed if you try to activate ACC at speeds below approx. 18 mph (30 km/h) without a vehicle ahead within range (approx. 100 ft/30 meters).

Therefore, vehicles or objects with low-reflec- tive surfaces may not be detected. Normally,the license plate and taillight reflectors givethe rear section of a vehicle ahead sufficientreflective surfaces to be detected.
NOTE
•Keep the windshield in front of the laser sensor free of ice, snow, dirt,etc., see City Safety – function(p. 198).
• Snow or ice on the hood deeper than2 inches (5 cm) may obstruct the sen-sor. Keep the hood free of ice andsnow.
• Do not mount or in any way attachanything on the windshield that couldobstruct the laser sensor.

Troubleshooting
If Windscreen Sensors blocked appears in
the information display, this indicates that the City Safety™ laser sensor is obstructed insome way and cannot detect vehicles aheadof you, which means that the system is notfunctioning. However, this message will not be displayed in all situations in which the sensor isobstructed. For this reason, the driver mustensure that the area of the windshield in frontof the sensor is always kept clean. The following table shows some of the situa- tions that can cause the message to be dis-played and suggested actions.
CauseAction
The area of the wind- shield in front of the sen-sor is dirty or covered byice or snow.Clean the windshield orremove the ice/snow.
The laser sensor's field of view is obstructed.Remove the obstruction.
NOTE
If a crack, scratch or stone chip should occur in the section of the windshield infront the laser sensor, contact a trainedand qualified Volvo service technician torepair or replace the windshield (see theillustration showing the location of the sen-sor in City Safety – function (p. 198)). Fail-ing to do so may result in reduced CitySafety™ functionality. To help prevent limited or reduced func- tionality, please also observe the following:
• Volvo recommends that cracks, scratches or stone chips on the wind-shield in front of the laser sensorshould not
 be repaired; in such cases,
the entire windshield should bereplaced.
• Before the windshield is replaced,contact a Volvo retailer to ensure thatthe correct windshield is ordered andinstalled. If the wrong type of wind-shield is used, this may cause CitySafety™ to function improperly or notat all. Volvo recommends the use ofonly Genuine Volvo ReplacementWindshields.
• When replacing windshield wipers, usethe same type or ones approved byVolvo.

City Safety – Laser sensor
The laser sensor
The upper decal describes the laser beam's classification and contains the following text: Invisible Laser radiation – Do not view directly with optical instruments (magnifiers) – Class1M laser product. The lower decal describes the laser beam's physical data and contains the text: IEC 60825-1:1993 + A2:2001. Complies with FDA performance standards for laser prod-ucts except for deviations pursuant to LaserNotice No. 50, dated July 26th, 2001 The laser beam's physical data is listed in the following table:
Maximum pulse energy2.64 μJ
Maximum average output45 mW
Pulse length33 ns
Divergence (horizontal × verti- cal)28° × 12°
NOTE
The function of aftermarket laser detectors may be affected by City Safety's laser sen-sor.
WARNING
The laser sensor emits light when the igni- tion is in mode II or higher, even if City
Safety™ has been switched off.
WARNING
Eye injury may occur if any of the following points are not followed: • It is essential that all pertinent instruc- tions be followed when handling laserinstruments. Testing, repairing, remov-ing, adjusting and/or replacing anycomponents in the laser sensor mayonly be done by a trained and qualifiedVolvo service technician.
• Do not remove the laser sensor(including removal of the lenses). Alaser sensor that has been removedbelongs to laser class 3B according tostandard IEC 60825-1. Devices in laserclass 3B present a risk of injury to theeyes.
• The laser sensor’s connector must bedisconnected before the sensor isremoved from the windshield.
• The laser sensor must be mounted inplace on the windshield before con-necting the sensor’s connector.
• Do not view the laser sensor (whichemits spreading, invisible laser beams)with optical instruments from a dis-tance of less than 4 inches (100 mm).
